Abstract
The present invention is directed to an intraocular lens delivery system with a multi-segment plunger. More particularly, the present invention relates to an intraocular lens delivery device that includes a disposable plunger tip segment that can be attached and removed from a reusable plunger base segment.
Claims16
A disposable plunger tip segment for an intraocular lens delivery system, the disposable segment comprising:
- an elongated body having a proximate end and a distal end;
- a fastening mechanism, which is a projection, a cavity or both, at the proximate end of the elongated body;
- and
- a pushing surface at the distal end of the elongated body;
- wherein:
- i. the elongated body and fastening projection or cavity are integrally molded of single polymeric material;
- ii. the fastening mechanism is configured to releasably, but securely and rigidly, attach the disposable segment to a reusable plunger segment of the intraocular lens delivery system;
- and
- iii. the single polymeric material has a flexural modulus of at least 3500 MPa.

An intraocular delivery system, the system comprising:
- an elongated housing having a length;
- a plunger having a disposable tip segment and a reusable base segment wherein:
- i. the reusable segment of the plunger is disposed within the housing and movable along the length of the housing;
- ii. the reusable segment includes a fastening mechanism at a distal end thereof;
- iii. the fastening mechanism of the reusable segment is a projection or a cavity;
- iv. the disposable segment includes an elongated body, a fastening mechanism at a proximate end of the elongated body and a pushing surface at a distal end of the elongated body;
- v. the fastening mechanism of the disposable segment is a projection or cavity;
- vi. the projection or cavity of the fastening mechanism of the reusable segment mates with the projection or cavity of the disposable segment of the fastening mechanism of the disposable segment to releasably, but securely and rigidly, fasten the disposable segment to the reusable segment;
- vii. the elongated body and fastening projection or cavity of the disposable segment are integrally molded of a single polymeric material;
- and
- viii. the single polymeric material has a flexural modulus of at least 3500 MPa.
